If cosA=4/5 and cosB=3/5 then find a,b,c
Answer:
a = 3, b = 4, c = 5
Step-by-step explanation:
Assuming we're working with a right triangle, where c is the hypotenuse, then using the definition of the cosine being the adjacent side over the hypotenuse, then we know:
a = 3, because it is the side adjacent to B
b = 4, because it is the side adjacent to A
c = 5, because it is the denominator in bot fractions
This of course assumes that there is no additional ratio in place. For example, if the lengths were instead 8, 6 and 10 respectively, then the cosines given would still be 4/5 and 3/5. Truthfully these only tell relative sizes of the sides, and not their absolute sizes.
Bonus: 2 points for vertex form or standard form, 5 points for both
Write the equation for the quadratic function the has a vertex at (3,-5) and includes
the point (-1,11)
9514 1404 393
Answer:
y = (x -3)² -5y = x² -6x +4Step-by-step explanation:
The vertex form of the quadratic equation is ...
y = a(x -h)² +k . . . . . . . . . vertex (h, k); vertical scale factor 'a'
Given the vertex, we can find the scale factor by substituting the given point values:
11 = a(-1 -3)² -5
11 = 16a -5
a = (11 +5)/16 = 1
So, the vertex form equation is ...
y = (x -3)² -5 . . . . . vertex form
Expanding this gives the standard form.
y = x² -6x +9 -5
y = x² -6x +4 . . . . . standard form
What is an improper fraction
An improper fraction is a fraction where the numerator is greater than the denominator
This is improper because you can't have more parts than the whole. WELL you can, math is confusing
You can have a mixed number, which says how many wholes there are and how many parts of a whole there is.
It's just called an improper fraction just like that I guess,
all you really need to know is that the numerator (the top number) is greater than the denominator (the bottom number), and to make it proper, you have to make it into a mixed number, but you have to use improper fractions to perform some operations.
You'll learn more about converting stuff from improper fractions to mixed numbers and vice versa to perform certain operations in the future, but for now, you just need to know what an improper fraction is.
I hope this helped, let me know if you have any questions.
Answer:
Step-by-step explanation:
An improper fraction is one where the magnitude of the numerator is greater than the magnitude of the denominator.
It is not enough to say that the numerator is greater than the denominator. You need to compare their magnitudes, i.e., their absolute values.
Suppose the fraction is 10/(-23). 10 is greater than -23, but 10/(-23) is not an improper fraction.
If the length of the shorter arc AB is 22 cm and C is the centre of the circle then the circumference of the circle is :
Answer:
The circumference of the circle is 176cm
Step-by-step explanation:
Step 1.
Figure out how many of those segments would fit in a whole circle
360/45=8
Step 2.
We know that the length of AB is 22cm so we multiply that by the number of segments in a whole circle
22×8=176

2. Charlie has a collection of marbles in three sizes, small, medium, and large. He has four times as
many small marbles as medium marbles. The number of large marbles is three more than five times
the number of medium marbles.
a. Write algebraic expressions to represent the number of small marbles, medium marbles, and
large marbles Charlie has. Write algebrauc expressions to represebt the number of small marbles, medium marbles, and large marbles charlie has.
Answer:
Step-by-step explanation:
The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m
Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.

Ralph Chase plans to sell a piece of property for $150000. He wants the money to be paid off in two ways minus−a short-term note at 12% interest and a long-term note at 9% interest. Find the amount of each note if the total annual interest paid is $15900.
The amount of the 12% note is $___. and the amount of the 9% note is $___
Answer:
The amount of 12% note is $90,000
The amount of 9% note is $80,000
Step-by-step explanation:
Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"
Selling price = $170,000
Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)
Given total annual interest = $18,000
Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)
18,000 = 0.12x + 0.09*(170000 - x)
18,000 = 0.12x + 15,300 - 0.09x
18,000 = 0.03x + 15,300
0.03x = 18,000 - 15,300
0.03x = 2,700
x = 2,700/0.03
x = 90,000
So, the amount of 12% note is $90,000
So long term paid money = $170,000 - $90,000 = $80,000
So, the amount of 9% note is $80,000

the product of a number and three, increased by 5, is 32. What is the number?
Answer:
3n+5=32
Step-by-step explanation:
this is an example of a 2-step equation.
First, subtract the 5,and cross that out on the left side
and do the same to the other side.
Then you have 3n=32 now, so all you have to do is divide by 3 and you have your answer.

factorise 2tv+t-10v-5
and make the k the subject
Answer:
(2v + 1)(t - 5)
Step-by-step explanation:
The first two terms of 2tv+t-10v-5 factor into t(2v + 1); the last two terms factor into -5(2v + 1). Thus, (2v + 1) is a factor of 2tv+t-10v-5:
2tv+t-10v-5 = (2v + 1)(t - 5)
The required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).
Given that,
To factorize 2tv+t-10v-5 and make the k the subject.
Factors can be defined by splitting the value into multipliable values.
What is simplification?The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here, according to the question to make k we have to factorize the 2tv+t-10v-5. So,
k = 2tv + t - 10v - 5
k = t( 2v + 1 ) - 5( 2v + 1 )
k = ( 2v + 1 ) ( t - 5 )
Thus, the required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).

Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.
Several minutes later, Raul decides to measure the water temperature again. He finds that the temperature changed by -0.6°F. What is the temperature of the water now? Show your work.
Answer:
32.6°F.
Step-by-step explanation:
The initial temperature of the water was 33.2°F. After several minutes, the temperature of the water changed by -0.6°F. So, the new temperature of the water is
33.2 + (-0.6)
=
(30 + 3) + [0.2 + (-0.6)]
=
33 + (-0.4)
=
33 – 0.4
=
32.6°F.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is miles per hour, with a standard deviation of miles per hour. Estimate the percent of vehicles whose speeds are between miles per hour and miles per hour. (Assume the data set has a bell-shaped distribution.)
About 68%
Given : The mean speed of a sample of vehicles along a stretch of highway is 66 miles per hour, with a standard deviation of 4 miles per hour.
i.e.
We assume the data set has a bell-shaped distribution (i.e. Normal distribution).
To find : The percent of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e. i.e . The percent of vehicles whose speeds are within one standard deviation from the mean.
According to the Empirical rule , about 68% of the population lies within one standard deviation of the mean.
It means , about 68% of vehicles lies within one standard deviation of the mean.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.
⇒ About 68% of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.
